This article introduced the application of ODEON in acoustics calculation.The modified value of sound center has been calculated,so the standard deviation is minimum.Establishment of semi-anechoic chamber model,import the model to ODEON to calculate.ODEON will export every point's SPL,take those data into MATLAB.comparing the deviation between real testing data and the simulation data of ODEON.In testing process,try to put the acoustic center of source on the extension line of microphone array.Establish the...
